VEHICLE-WHEEL.

To all whom it may concern:

Be it known that I, ISRAEL PASCAL, resident of 2O Rivard street, in thecity and district of Montreal, Province of Quebec, Dominion of Canada, asubject of the King of Great Britain, have invented certain new anduseful Improvements in Vehicle- Vlfeels; and I do hereby declare thatthe following is a full, clear, andexact description of the same.

The invention relates to an improvement in vehicle wheels, as describedin the present specification and illustrated in the accompanyingdrawings that form part of the same.

The invention consists essentially of the novel construction andarrangement of parts whereby the cushion effect is attained with metalshoes resiliently supported in a rigid tire case.

rIhe objects of the invention are to devise an indestructible easyriding tire, to eliminate the pneumatic feature in the tread portion ofthe tire, and generally to provide a simple cheap and durable form ofvehicle tire.

In the drawings, Figure 1 is a perspective view of the wheel complete.Fig. 2 is an enlarged vertical part sectional view of the wheel. Fig. 3is an enlarged cross sectional perspective view of a portion of the rimand tire. Fig. 4 is an enlarged cross sectional perspective view of aportion of the outer part of the tire case. Fig. 5 is an enlarged crosssectional perspective view of a portion of the rim or inner part of thetire case. Fig. 6 is a detail of a metal shoe. Fig. 7 is a detail of arubber filling block for said shoe. Fig. 8 is a sectional perspectivedetail of a portion of the shoe supporting band.

Like numerals of reference indicate correspending parts in each gure.

Referring to the drawings, 1 is the rim of the wheel, semicircular incross section having the flanges 2 at the outer edges and forming theinner half of the tire case, said rim being preferably formed of metal,

3 is the outer half of the tire case, also preferably formed of metaland semi-circular in cross section and fitting into the flanges 2, saidouter half of the tire case Specification of Letters Patent.

having cross shoe slots 4 suitably dista-need one from the other.

5 are the shoes, each having the arc` shaped. tread portion 6terminating in the olf-set 7.

8 are pins projecting from the off-sets 7.

9 are rubber blocks correspondingly shaped and tted into the shoes 5.

10 is a circular band having the holes 11 through which the pins 8project, said pins being splayed over on the inner side of said band,said .shoesV 5 being correspondingly spaced on the band 10 to thedistances between the shoe slots 4.

12 is a ring of rubber preferably solid and semi-circular in crosssection and fitted into the rim 1 forming a bed on which the circularband 10 is mounted.

13 are distance blocks of rubber between the rubber blocks 9 and betweenthe lianges 14 extending inwardly from the edges of the shoe slots 4.

It will be thus seen that when the parts are assembled, the shoes 5,which are opposite the shoe slots 4 extend therethrough beyond the rigidouter part of the case 3, the said part 3 and the said rim 1 beingsuitably secured together by bolts or rivets or any other form offastening.

15 are spokes of any suitable pattern and here shown as of flanged metalformation each having the base 16 rigidly secured to the rim 1 andextending therefrom tothe central hub 17.

In the use of this invention in the running gear of vehicles, the weightof the vehicle is supported from the ground directly on the shoes 5which are preferably of a stiff spring steel and have sharp grippingedges, so that on slippery roads, either ice, snow or otherwise, theresiliency of the inner part gives the dshoe a forward or rearward gripon the roa There are two directions to the movement of the cushionpartformed by the movement of the inner rubber cushion and the springsteel band, that is to say, the direct downward weight of the vehiclewill have the tendency to force in the rubber in a radial line with thespokes, while in the gripping of the shoes, in the forward or rearwardmovement, the bend of the spring band forces the rubber in anotherdirection. These two movements of the rubber are important as they addmaterially to eiiciency in operation.

Vhat I claim as my invention is:

1. In a vehicle wheel, a hollow metallic tire case having transversespaced slots in its periphery, an annular spring metal band disposedwithin said tire case and having spring metal loops secured transverselythereacross and projecting through said slots in the tire case, meansfor resiliently supporting said metal band disposed therebeneath, a huband means for supporting said tire case from said hub.

2. In a vehicle wheel, a hub, spokes eX- tending from said hub, a hollowrim of substantially semi-circular formation in cross section rigidlysecured to said spokes, a ring of rubber substantially semi-circular incross .section forming a resilient bed in said rim, a circular springband mounted on said rubber bed, a plurality of spring metal shoeshaving an arc-shaped tread portion and rigidly secured at their upperends to said band and suitably spaced, an outer ring case vsemi-circular in cross section having cross slots through which saidshoes project rigidly secured to said inner case, and distance blocksbetween said shoes.

3. In a vehicle wheel, a hub, spokes eX- tending from said hub, aho-llow ring forining the inner part of a tire case and rigidly securedto said spokes, a rubber ring forming a resilient bed in said rim, acircular spring metal band mounted on said resilient bed, a plurality ofspring metal shoes having arc-shaped tread portions and rigidly securedto said metal band at suitable distancesy apart, rubber blocks fillingin said shoes, rubber distance blocks between said shoes, and an outerring casing substantially semi-circular in cross section having crossslots' through which said shoes project rigidly secured to said rim.

Signed at the city and district of Montreal, Quebec, Canada, thistwenty-first day of April, 1911.
